I switched over to plain water tonight. It started with my 300 PPM tap water and it went to 400 after the first run and up to 420:thumbsup: after the second and I think it's leveled off. I'm going to leave it for the rest of the feeds tonight and change it out again tomorrow and try around 900 PPM with full bloom nutes.

My sister got me Jorge Cervantes's Medical Grow Bible for a late Christmas gift tonight, and I've been reading it non stop. From what I read in there, it definitely sounds like it was salt buildup. Not that I doubted either of you though!

dejayou30 Reviewed by dejayou30 on . Its Always Something... I think this is a phosphorus deficiency, but I am not totally sure. The edges are crispy and the new small leaves around the buds have yellow, crispy, turned down tips. The guide I read said a little P deficiency in flower is normal, but if P is what it is, I think I have more than a little. What should I do? PPM is 1150, pH is 5.6, double checked with liquid pH kit. They are starting Week 4 tomorrow. The last pic is what I would say is the worst looking one. Rating: 5
